Unlock the power of quantitative analysis with our Beer-Lambert Law Calculator. Easily determine the absorbance of a solution given its concentration, molar absorptivity, and path length, or find the concentration from absorbance readings. Essential for chemistry, biology, and biochemistry students and professionals in spectrophotometry.
Formula:
The Beer-Lambert Law describes the relationship between the absorbance of a solution and its properties:
A = εbc
- A: Absorbance (unitless)
- ε: Molar Absorptivity (also Extinction Coefficient), typically in L mol-1 cm-1
- b: Path Length of the light through the sample, typically in cm
- c: Concentration of the absorbing species, typically in mol L-1 (M)
